MASSAGING MACHINE.

Application filed December 2, 1926. Serial No. 152,083.

This invention relates to a motor driven n'lassage machine for massaging, rubbing or nuini nilating the scalp of the human head of that type shown and disclosed in application Serial No. 136,421, filed September 520, 19:26.

The principal object of this invention is to so construct the various elements of the mechanism, and particularly the housing therefor, as to facilitate its manufacture and as stnnhly. .lPly means of this invention, the various parts of the machine are brought together and combined in different units hearing such relation to each other as to permit each unit to be built up separately, and then readily joined with the other units to complete the assembly.

The full nature of the invention will be understtmd from the accompanying drawings and the following description and claims:

In the drawings, Figure 1. is a plan view looking down upon the machine. Fig. 2 :is a plan view of one side of the machine, slmwing the other side in perspective, with parts broken away. Fig. 3 is an end clevationofone side of the machine. Fig. 4 is a front elevation o t the parts in assembling position before assembly, and slmwing portions thereof in ca. .4 section. Fig. is a front elevation of the con iplete machine after assembly of the parts shown in Fig. at, one side thereof being shown in. central vertical section. a

In the drawings, there is shown a massage nnmhine or mechanism comprising an chic tric motor rigidly secured to a saddledike central housing 11, the ends of said housing extending at an angle to each other as best shown in Fig. at. Positioned in said housing there is a htn'izontally-extending moton driven shaft 12 having itsfree end mounted in a suitalile thrust end bearing 13 secured in said housing. Mounted on the shaft 13 and licyed thereto there is a Worm l4 driven by the motor 10 and so positioned to mesh with the worm gears 15 when the units are assembled, shown in Figs. 2 and 5, so as to cause the rotation thereof. It will be noted that the gears 15 are positioned :in planes extimding at an angle to each other, and by reason. of their being driven by a common worm, are rotated in opposite directions.

Each of said gears is keyed to a shaft 16 and each of said shafts is provided with a reduced bearing surface 17 mounted in the bearings 18 formed of suitable bearing metal securely fitted between the adjacent ends of the housing 11 and the end housings 19.

The lower end of the shaft 16 is provided with a head 20 and eccentrically keyed to an annular rotating bloc 21 which is rotatably mounted in a driving collar :22 to which is St:- cured a driving arm 23. a

The arms extend below and exteriorlv of the housings .11 and .19 in planes parallel to their respective gears 15, having their free ends secured to the driving pi "S1271: rotatably mounted in thebushings Il'loth the bushings and the driving collars 22 are formed of suitable impregnated wood for providing a bearing surface, said bushings being moun l in their respective massaging elements .llhe housing 11 is provided with a pair of guide pins 27 extemliiig from each end thereof, upon which the massaging elements 2:) are adapted to slide and be supported, said elements being provided with corresponding reeesses for receiviugsaid pins. Thus the movement imparted to said elements by the rotation of the gears 15 will impart a reciprocal ing movement, said two elements sliding back and forth upon the pins 27, which will maintain them during such mownnents in a straight line. Said elements are provided on their underside with a plurality of prongs 29 and covered with a suitable rubber massage pad 30 for engaging and manipulating the scalp. As heroin shown, the machine first built up in five different units, the central unit comprising the motor, driving shaft and worn'i mounted on the housing 11, the two mani 'mlating units comprising the worm gears 15, the pads and an intermediate actuating mechanism, and the end units or housings 19 which are provided with upwardlyextending handles 31, all of which is best illustrated in respective positions by Fig. :11. The units are then readily assembled by merely sliding the massage element units into position on the pins 27 so that the gears 15 mesh with the worm 14. Theend housing units 19 are then mounted over a portion thereof so that the gears and associated driving mechanism will be completely housed and held in position by thesecuring of the housings 19 to the central housing 11. through the medium of the screws 32. i 7

It will be noted in Fig. 3 that the massaging element is provided with a rigid central portion having end portions which are hingedly connected thereto at 33 and normally maintained in the position shown by full lines through the medium of the compression tit) tour of the head so as on oi saiit springs under ten- Soon to )orinit tho ohanont to cootmin to inii'atoros of the s :aip oit gl'iator rai'iins.
